My present invention relates to automobile door` windows and more particularly to automobile door windowventilatorsv which are electrically operated from a remote control electrical switch located on the door panel or on some other place within the automobile door. Y

It is a well-known fact that in the present-day development of automobiles and other modern mechanisms that there is a growing demand Vand inclination toward electrically operated devices sometimes referred to, in the trade, as push button control. A Y

It is evident to all that devices which `are convenient and easily operated are the devices sought by the, great majority of individuals; therefore the present invention has been developed and perfected for the purpose of attempting to satisfy this growing demand.

It is also quite evident that certain mechanical results'must be obtained in any device of this nature if it is to be offered the public in a motor Certain of these results are hereinafter pointed out in the following specification.

The principal object of my invention 4is an improved ventilator operating device for automobile window ventilators and the like;

Another object is an improved automobile window ventilator which is electrically operated;

Still anothervobj'ect is an improved automobile window ventilator winch isA electrically operated and in which the said ventilator is at all times locked against operation from the ventilator end or, in other words, cannot be operated excepting from the inside areaof the automobile by means of an electrical switch therein'mounted;

A still further object is an improved automobile door ventilator which is electrically operated from the inside of the vehicle which not only opens the ventilator but closes it and which leaves the ventilator in a locked condition at any point of operation vsuch that the ventilator cannot be operated in either direction excepting by the manipulation of the control switch located within the vehicle, and

Other objectsand novel features comprising the construction and the operation oftheyimj proved automobile Window ventilator control mechanism will be apparentes the description and operation of the same progresses.

Fig. 5 is a modincation of the'apparatusfshown in Figs. 1 to 4 inclusive. In thislgure, as in previous figures, certain portions -are broken away for convenience and other portionslareshownin part elevation and part cr's's"'secti 0n, some porswinging variety being pivoted at its bottom in the frame I4 of the door IIl.` I,

Located within the lower panel of the door I0 is a horizontally disposed housing I5 which ispermanently attached to the door frame ,or the outer door panel whichever is most convenient or practical. Within this housing I5 is located a .reversible kelectrical motor I6 from which extends a drive shift `II on the free endgof which is located a wormgear I8. The wormvgear I8 is engaged with a worm wheel I9 `which is pivoted within the housing I5. -Theeleotrical motor I5 is a reversible motor such that the Worm wheel I9 may be operated in a clockwise direction'or in a counterclockwise direction according Vto` the desire o f the operator. Any convenient reversible electrical switch may be used to reverse the said motor I6. For a morel comprehensive disclosure of a specic drive mechanism, asY indicatedin the present drawings, reference is-directedqto'my copending application Serial No. 519,599, led January 25, 1944, Vin which the complete electrical motor Vdrive is disclosed. However, in my present application I wish to point outthatthe present invention is not dependent upon the specific electrical'drive shownin my above copending ap,- plication. as any reversible electrical motor drive may be used for the operation of the ventilator window l2 in which there is an equivalent of the driven worm wheel I9 on the driving axis 0f which there is a drive pinion, as the pinion 20 ine dicated in Fig. 1. For Vthe purpose oi tliepresent applicationreversible driving. power is derivedY fromia'pinion 20 mounted ori-thel'iousing I5,k

the said pinion 20 is engaged with a rack member Y 2 I. The said rack member is supported in a horizontal slidable mannerY on the housing I by means of slide holdingmembers such as those shown at 22.' These slide members may be weld- -edor otherwise aflixedto the housing l5 in any convenient mannerso that the rack 2|is Vhorie zontally slidable, on. the housing 5. O n the end .othefrack remote from the pinion Z thereis engaged asegmentalgear which is Lpivoted Qnthe housingv by means of the stud Ilv which is secured in theside of the housi ng v| 5, 'see Fig. 4. Within the housing I5 I Vhave located a vertical 4 of the apparatus in which that casing I5 is provided Vwith a slightly dilerent slideway 40 in which is positioned a slide member 4I which is hollow and in the head portion of which is lo-V cated an orice 42 through which is directed a spirally twisted fiatbar member 43 which is secured to the member 44 permanently connected withthe window ventilator portion I 2. With the exception of the substitution of the member 43 for the cylinder 29 and the substitution of the hollowV slide member 4| for the slide member 25 the rest of the apparatus is identical with that member'i125, whichextends upwardly above the I yupper.surface of the housingl VAt a p oint just ,above vthetop of. the housing AI5 onV the slide 25 Ihave locatedanother stud 26 which is secured jin; the slidezfand on which ispivoted aconnecting rod member 2l. 'Ihe opposite end of the connecting lever 2 1 Visjourn'alled around another studindicated at `28 which is similar to the stud 21, the stud 28 being xed Vto the lower portion of the segmental gear 23,V as shown inthe draw- Onrthelower side oi thefwindow ventilator ymember |/2 I have fixed a cylinder member'Z. i This cylinder 253 maybejjournalledat its upper Y pivoted. endin any convenient manner within the @door f ramel4 such that when the cylinder Y 29 isrotated,within the frame of the door I 0 the window ventilator I2 will swing in a horizontal viewed The cylinder 29 is provided with double spiral 'Y tracks 30 and 3| in which voperates'a pin member 32. By an yinspection of Fig. 4 it will be noted that the pinmember 3271s located in theupper portion of the slide member 25, ,as indicated at 33. This portion 33 of the slide V2 5 is comparable to a similar construction in the upper portionsv of a connecting rod in internal combustion eri-` gines and the pin which is tightly secured in the portionf33 is comparable to a wrist-pin of the said `internal combustion engine, to the eiect that when the slide member 25 is moved in a vertical direction the pin 32 will slide in the tracks and 3|Y and because of the fact that the rslide 25 cannot revolve, the cylinder which is revolvable in the door frame I4 will revolve; therefore the ventilator window |12 will be'-aiee'ted and Vcaused topivotinthe door frame I4.

It willthus beseen that when the electrical motor I6 is operated in either rof its two reversi-v I ble directions, the raclf: 2| will slidein one vor another Q; oposite direction and therebyY causethe cylinder 24 torotate on its axis in a correspond- .ing direction, v thereby causing the ventilator member` |2 to swingeither to a closed or an open positicnasthecasemay be. Y

In Fig, 5 I' have shown a slight modication i plane either to the right or the left-hand side, as

shown in Figs. 1 to 4. Y Y

In operation, the ventilator window 2 may be opened or closed, as the case may be, by means of the motorl I6. When the motor I6 is electrically energized in one direction, the pinion2 will move the rack 2| to the left-hand side, as shown in Fig. 3 thereby raising the connecting link 2'I which causes the slide member 25 to slide upward'lyvin the slideways24 located in thehousing 5. -When this action takes place, the trans-V versally: located pin lined inthe upper portion of the slide member 25w`ith end portions'engaging in the spiral grooves 3i]Y and 3| turns vthe cylinder 29 in the'door frame I4 andv thereby causes the ventilator window 'I2' which is attached tothe cylinder lilfll'to swing open, `as shown in Fig. 3. In a reverse manner 'the windowV I2 is closed when the directionof the reversible motor I6 isoperated in the other direction Yreturning the apparatus yto the position shown in Fig. 2. In the modicat'ion shown in Figs. and 6 (the cylinder 29 and slide 25 is substituted for by the spiral member 43 and 4| respectively, the rest of the mechanism being exactly the sameand the Vsame results are attained with -th'evvindow I2 as previously described where the cylinder 29 is used.

For thepurpose of simplicity I haveshown'my invention in very simpledrawings .in whi'chthe.

basic structure is set forth .in its simplest forms; yet itis to `be understood ithat I may vary the details of `'this strutcurefior shop purposes or for production requirements withinwide latitude without departing from the spirit of the inven Y tion.
